Description

Technical Field

[0001] The utility model relates to a novel heater. Background Art

[0002] Electric heaters can be widely used in various civil and public buildings such as residential buildings, offices, hotels, shopping malls, hospitals, schools, train carriages, mobile heating, simple mobile houses, etc.

[0003] The thermal deformation reserve of existing electric heaters is usually set in the width direction. For example, the electric heater disclosed in CN209893513U requires sufficient gaps to be reserved on the two side panels of the rear cover in the width direction to cope with thermal deformation, so that the width of the electric heater is usually wider and not compact enough, and the length direction does not reserve enough space for thermal expansion and contraction deformation for the front cover.

[0004] The electric control box is the main device for controlling the electric heater, and is usually directly connected to the side end of the heat radiation component, which makes the electric control box easily affected by high temperature, affecting its operation. In addition, the wire protection sleeve used for the wires between the electric control box and the heat radiation component is usually larger in diameter to facilitate the installation and insertion of the wires, resulting in a larger gap between the wires and the wall of the wire protection sleeve, causing the heat in the heat radiation component to enter the electric control box through the wire protection sleeve, causing the electric control box to work in a high temperature environment, affecting its service life or normal operation.

[0005] In addition, the cover of the electric heater is generally made of aluminum (aluminum alloy). Since aluminum deforms greatly after being heated, the heating tube used to provide heat source is generally installed in the mounting groove of the upper cover. At room temperature (when not in use), the heating tube and the mounting groove are tightly fitted, but when in use (after heating), the gap between the mounting groove and the heating tube will become larger. The higher the temperature, the larger the gap; after being heated, the heating tube will oscillate and hit the side wall of the mounting groove, making a rattling sound, which can easily cause users to mistakenly believe that the electric heater is damaged. Utility Model Content

[0007] The technical solution of the utility model is that a heating tube is installed on the inner wall of the upper cover, the upper cover is slidably connected to the lower cover shell, and one end of the upper cover is fixed to one end of the lower cover shell so that the upper cover can be thermally deformed and stretched toward the other end of the lower cover shell, and one end of the lower cover shell is spaced apart and connected with an electric control box.

The upper and lower parts of the connecting pieces are provided with longitudinal guide grooves matching the longitudinal guide rails corresponding to the lower cover shell and the upper cover, and a heat insulation plate arranged along the length direction is installed between the two connecting pieces.

[0010] Furthermore, a sealing plate is installed at the other end of the upper cover to form a thermal deformation expansion and contraction distance with the other end plate, and a shield plate is horizontally installed in the lower cover shell and is located on the lower side of the sealing plate. One end of the shield plate is abutted against the other end plate, and the longitudinal length of the shield plate is greater than the thermal deformation expansion and contraction distance.

[0011] Furthermore, longitudinal slots are provided on the inner walls of both side plates of the lower cover shell along the length direction, both ends of the shield plate extend into the longitudinal slots, and a limit baffle abutting against the other end of the shield plate is installed in the lower cover shell.

[0012] Furthermore, a longitudinal installation groove composed of a pair of arc-shaped plates is arranged in the upper cover along the length direction, the heating pipe is embedded in the longitudinal installation groove, and a reinforcement structure of the heating pipe is arranged in the cover.

[0018] 1. The heater has a compact structure. By fixing one end of the upper cover to an end plate and setting a thermal deformation expansion spacing between the other end of the upper cover and the other end of the lower cover, a thermal expansion deformation space in the length direction is reserved for the upper cover, which helps to achieve thermal deformation of the upper cover along the length direction and helps to automatically adjust the thermal deformation of the upper cover along the length direction.

DETAILED DESCRIPTION

[0030] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0031] refer to Figures 1 to 7

[0032] A novel heater includes a groove-shaped lower cover 1 and a groove-shaped upper cover 2. The upper cover is slidably connected to the lower cover and one end of the upper cover is fixed to one end of the lower cover so that the upper cover can be thermally deformed and telescoped toward the other end of the lower cover. Specifically, both ends of the lower cover are fixed with end plates 11 extending upward by screws, and a heating tube 3 is installed on the inner wall of the upper cover. The upper cover is slidably connected to the lower cover and one end is fixedly connected to an end plate and covers the end of the upper cover. There is a thermal deformation telescopic spacing 12 between the other end of the upper cover and the other end plate, and the thermal deformation telescopic spacing provides telescopic space for thermal deformation of the upper cover. An electric control box 6 is installed at one end of the lower cover away from the thermal deformation telescopic spacing.

[0033] In this embodiment, both side plates of the lower cover shell and the upper cover are provided with longitudinal guide rails 13 and 21 along the length direction, and both side plates of the lower cover shell are provided with connecting parts 4 on the inner sides. The upper and lower parts of the connecting parts are provided with longitudinal guide grooves 41, and the longitudinal guide grooves cooperate with the corresponding longitudinal guide rails of the lower cover shell and the upper cover, so as to realize the connection between the upper cover and the lower cover shell, and help to provide a deformation gap for the thermal deformation and expansion of the upper cover and the lower cover shell.

[0034] In this embodiment, the longitudinal guide rail is in a horizontal fold shape (inverted L shape) and is arranged on the inner side of the free end of the side panel of the corresponding lower cover shell and upper cover, and the longitudinal guide rail is integrally formed with the corresponding side panel of the lower cover shell and upper cover; the longitudinal guide groove is in a vertical fold shape (inverted L shape), and a horizontal partition 42 is arranged between the two longitudinal guide grooves.

[0035] In this embodiment, the inner side of the connector is provided with longitudinal slots 43 along the length direction, and a heat insulation board 5 arranged along the length direction is installed between the two longitudinal slots, and the heat insulation board is a galvanized board. A chamber is formed between the heat insulation board and the upper cover, which helps to reduce the heat flow into the lower cover, reduce heat loss, and help to radiate heat outward through the upper surface of the upper cover.

[0036] In this embodiment, a sealing plate 22 is fixedly installed at the other end of the upper cover by screws to form a thermal deformation expansion and contraction interval with the other end plate, and a shielding plate 14 is transversely installed in the lower cover and located at the lower side of the sealing plate, one end of the shielding plate is in contact with the other end plate, and the longitudinal length of the shielding plate is greater than the thermal deformation expansion and contraction interval. Thus, the lower cover and the upper cover are both closed, reducing the heat loss from the lower cover to the outside and improving the aesthetic effect.

[0037] In this embodiment, the two ends of the heat insulation plate can be respectively abutted against the sealing plate and an end plate, which helps to reduce the heat entering the lower cover shell.

[0038] In this embodiment, the inner walls of the two side plates of the lower housing are provided with longitudinal slots 15 along the length direction, and both ends of the shield plate extend into the longitudinal slots, and a limit baffle 16 is installed in the lower housing to abut against the other end of the shield plate. The longitudinal length of the shield plate can be 1.5 to 2 times the thermal deformation telescopic spacing.

[0039] In this embodiment, a longitudinal mounting groove 23 composed of a pair of arc-shaped plates is provided in the upper cover along the length direction. The number of the longitudinal mounting grooves can be two or more, and the arc-shaped plates are integrally formed with the upper cover. The heating tube is embedded in the longitudinal mounting groove, and a reinforcement structure of the heating tube is provided in the cover. During the use of the heater, the longitudinal mounting groove will be deformed due to heat, so that the gap between the longitudinal mounting groove and the heating tube increases, and the heating tube will vibrate and collide to make a rattling noise. The reinforcement structure helps to limit the heating tube in the longitudinal mounting groove, which helps to avoid the generation of abnormal noise.

[0040] In this embodiment, the reinforcement structure includes a transverse convex plate 24 arranged along the length direction of the outer wall of one of the arc-shaped plates, one end of a pressing plate 25 is pressed on the heating tube, and the other end of the pressing plate is anchored on the transverse convex plate by an anchor, thereby pressing the lower side of the heating tube to prevent the heating tube from colliding with the longitudinal installation structure. The pressing plate is L-shaped, and at least one pressing plate is arranged on each heating tube. The pressing plate and the heating tube have two pressing blocks at the end that matches the heating tube to improve the stability of contact with the heating tube.

[0041] In this embodiment, the end of the lower housing away from the thermal deformation telescopic spacing is installed with an electric control box through a pair of connecting rods 61, the connecting rods pass through the electric control box and one end of the connecting rods extends into the lower housing to be screwed with the lower housing, and the connecting rods and the electric control box are locked by bolts. The connecting rods have an exposed section (a section not extending into the electric control box and the lower housing) between the electric control box and the lower housing, so that there is a heat insulation spacing 62 between the electric control box and one end plate of the lower housing, which helps to prevent the heat on the upper cover from being directly transferred to the electric control box; a light-transmitting cover plate 63 is embedded on the upper side of the electric control box, which helps the value displayed by the display module in the electric control box to be transmitted through the light-transmitting cover plate.

[0042] In this embodiment, a wire protection sleeve 7 is installed between the electric control box and one end plate, which helps the power line in the electric control box to pass through the lower cover shell to control the power supply of the heating tube; the wire protection sleeve can be made of silicone material. An extension section 71 is provided at one end of the wire protection sleeve extending into the electric control box, and an annular recess 72 is provided on the outer wall of the extension section to reduce the wall thickness; a cable tie is tied on the annular recess, and the cable tie can be a plastic cable tie, so that after the wire is installed, the port of the extension section is tightened to reduce the gap between the wire and the tube wall, which helps to reduce the heat in the lower cover shell from entering the electric control box and prevent the electric control box from being affected by high temperature. It is also possible to insert a silicone sheet into the tube of the extension section after the wire passes through the wire protection sleeve, and then tighten it with a cable tie, which helps to further reduce the gap.

[0043] In this embodiment, the wire protection sleeve is provided with a thickened wall section with an annular protrusion between the electric control box and the lower cover shell, which is used to limit the electric control box and the lower cover shell and ensure the distance of the thermal insulation distance between the electric control box and the lower cover shell.

[0044] In this embodiment, in order to better radiate heat, the upper side surface of the upper cover is provided with longitudinally arranged radiation ridges 26 at intervals along the width direction; the back side of the lower cover is provided with hanging slots 17 along the length direction, so as to facilitate the hanging installation of the heater.

[0045] In this embodiment, the upper cover, the lower cover shell and the connecting parts are all made of aluminum alloy material.

[0046] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection to each other can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0047] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0048] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0049] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
